Intercom VOX Menu
(not used for ground applications)
The active frequency is indicated in the top line of the display, while the “IC VOX” label and below
this a bar graph with numerical value are shown in the bottom line.
By means of the “ROTARY ENCODER“ the intercom VOX threshold can be changed from -30
(most sensitive, even a very low microphone signal already triggers the VOX threshold for Intercom
operation) to +10 (VOX is less sensitive and only high microphone signals trigger the VOX
threshold for intercom operation).
Note:
At a setting for VOX threshold of
-15 a
convenient behavior of the VOX should be
achieved in most vehicles. This requires that mike sensitivity had been correct
adjusted (installation setup). If the mike sensitivity is incorrect adjusted, VOX may
work not satisfying.
By changing the VOX threshold level to above +10, VOX can be switched “OFF”. In this case,
“OFF” replaces the numerical value indication (see figure below):
With VOX switched “OFF”, activation of intercom operation using the external intercom switch (/IC
discrete input) is still possible at any time.
The VOX threshold level cannot be adjusted if the VOX is forced to be “OFF” (due to Enabled
speaker in current audio configuration).
